以編程方式從ipad發送數據到wifi打印機

Question

我正在創建一個ipad應用程序，我想以編程方式將數據發送到wifi打印機。是否有任何API或示例代碼可用於實現此目的？

謝謝。

Answer 1

我認爲正常的打印API將使用AirPrint來完成此操作。 http://developer.apple.com/library/IOs/documentation/2DDrawing/Conceptual/DrawingPrintingiOS/Printing/Printing.html

此外，有一個名爲Printopia偉大的應用程序，讓你的Mac作爲一個AirPrint的主機：http://www.ecamm.com/mac/printopia/

UIPrintInteractionController * PIC = [UIPrintInteractionController sharedPrintController]

如果（PIC & & [UIPrintInteractionController canPrintData：self.myPDFData]）{

pic.delegate = self; 

UIPrintInfo *printInfo = [UIPrintInfo printInfo]; 

printInfo.outputType = UIPrintInfoOutputGeneral; 

printInfo.jobName = @"PrintPdf"; 

printInfo.duplex = UIPrintInfoDuplexLongEdge; 

pic.printInfo = printInfo; 

pic.showsPageRange = YES; 

pic.printingItem = self.myPDFData; 

void (^completionHandler)(UIPrintInteractionController *, BOOL, NSError *) = 

^(UIPrintInteractionController *pic, BOOL completed, NSError *error) { 

    if (!completed && error) 

     NSLog(@"FAILED! due to error in domain %@ with error code %ld", 

       error.domain, (long)error.code); 
}; 
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { 

    [pic presentFromRect:self.printButton.frame inView:self.view animated:YES completionHandler:^(UIPrintInteractionController *printInteractionController, BOOL completed, NSError *error) { 
    }]; 

} else { 
    [pic presentAnimated:YES completionHandler:completionHandler]; 
} 

}
